MC16S084T3B
The family of 16M Synchronous Dynamic RAMs is fabricated using 0.45µ
CMOS high–speed silicon gate process technology. It includes devices
organized as 2 banks x 2,097,152 words x 4 bits, 2 banks x 1,048,576 words
x 8 bits, and 2 banks x 524,288 words x 16 bits. Advanced circuit design and
fine line processing provide high performance, improved reliability, and low
cost.
Fully synchronous operations are referenced to the rising edge of the clock
input and can achieve data transfer rates up to 100 MHz. These devices are
ideal for main memory in applications such as workstations, microcomputers,
and refresh memory in CRTs.
These devices are packaged in a standard 400 mil thin small outline
package (TSOP).

positive edges of CLK. When RAS and CS are asserted low
and CAS is asserted high, either the Bank Activate command
or the Precharge command is selected by the WE signal.
When WE is asserted high, the Bank Activate command is
selected and the bank designated by BA is turned on to the
active state. When WE is asserted low, the Precharge com-
mand is selected and the bank designated by BA is switched
to the idle state after precharge operation.
PIN FUNCTION
CLOCK INPUT (CLK)
The CLK input is used as the reference for SDRAM opera-
tions. All operations are synchronized to the positive edges
of CLK.
CLOCK ENABLE (CKE)
The CKE input is used to suspend the internal CLK. When
the CKE signal is asserted low, the internal CLK is sus-
pended and output data is held intact while CKE is asserted
low. When the device is not operating in the burst cycle, the
CKE input controls the entry to the Power Down mode.
COLUMN ADDRESS STROBE (CAS)
The CAS input defines the operation commands in con-
junction with the RAS and WE inputs, and is latched at the
positive edges of CLK. When RAS is held high and CS is
asserted low, the column access is started by asserting CAS
low. Then, the Read or Write command is selected by assert-
ing WE low or high.
BANK ACTIVATE (BA)
The 16M SDRAM family devices are organized as two
bank memory cell arrays. The BA input is latched at the time
of assertion of the operation commands and selects the bank
to be used for the operation. Whe BA is asserted low, bank 0
is selected. When BA is asserted high, bank 1 is selected.
WRITE ENABLE (WE)
The WE input defines the operation commands in conjunc-
tion with the RAS and CAS inputs, and is latched at the posi-
tive edges of CLK. The WE input is used to select the Bank
Activate or Precharge command and Read or Write com-
mand.
ADDRESS INPUTS (A0 – A10)
The A0 – A10 inputs are addressed to access the memory
cell array, as in the following table.
DATA INPUT/OUTPUT MASK (DQM OR LDQM, UDQM)
Part Number
M116S163AST
MC16S084T3B
MC16S044T3B
Row Address
A0 – A10
Column Address
A0 – A7
The DQM input functions as the output enable in a read
cycle and as the input data mask in a write cycle. When DQM
is asserted high at the positive edges of CLK, output data is
disabled after two clock cycles during a read cycle, and input
data is masked at the same clock cycle during a write cycle.
In the M116S163AST, the LDQM and UDQM input func-
tions as byte data control. The LDQM input can control DQ0
– DQ7 in a read or write cycle and the UDQM can control
DQ8 – DQ15 in a read or write cycle.
A0 – A10
A0 – A8
A0 – A10
A0 – A9
The row address bits are latched at the Bank Activate
command and column address bits are latched at the Read
or Write command. Also, the A0 – A10 inputs are used to set
the data in the Mode register during a mode register set
cycle.

The DQ0 – DQ15 input and output data are synchronized
with the positive edges of CLK. In the MC16S044T3B and
MC16S084T3B, these pins are DQ0 – DQ3 and DQ0 – DQ7.
The CS input controls the latching of the commands at the
positive edges of CLK when CS is asserted low. No com-
mands are latched as long as CS is held high.
OPERATION MODE
ROW ADDRESS STROBE (RAS)
Fully synchronous operations are performed to latch the
commands at the positive edges of CLK. See the following
Truth Table for operation commands.
The RAS input defines the operation commands in con-
junction with the CAS and WE input and is latched at the

COMMAND FUNCTION
Read with Auto Precharge
(RAS = H, CAS = L, WE = H, BA = Bank, A10 = H,
A0 – A9 = Column Address)
Bank Activate
(RAS = L, CAS = H, WE = H, BA = Bank,
A0 – A10 = Row Address)
The Read with Auto Precharge command automatically
performs the precharge operation after the read operation.
This command must not be interrupted by any other com-
mand.
The A9 input is a don’t care for the MC16S084T3B and the
A8, A9 inputs are don’t care for the M116S163AST.
The Bank Activate command activates the bank desig-
nated by the BA (Bank Activate) signal.
Row addresses are latched on A0 to A10 at the time of this
command and the cell data is read out of the sense ampli-
fiers. The maximum time that each bank can be held in the
active state is specified as t
(max).
Mode Register Set
RAS
(RAS = L, CAS = L, WE = L,
BA, A0 – A10 = Register Data)
Bank Precharge
(RAS = L, CAS = H, WE = L, BA = Bank, A10 = L,
A0 – A9 = Don’t Care)
The Mode Register Set command programs the values of
CAS latency, Addressing mode, and burst length in the Mode
register. The default values of the Mode register after power–
up are undefined, therefore this command must be issued at
the power–up sequence.
The Bank Precharge command precharges the bank des-
ignated by BA. The precharged bank is switched from the
active state to the idle state.
Also, this command can be issued while both banks are in
the idle state.
Precharge All
(RAS = L, CAS = H, WE = L, BA = Don’t Care, A10 = H,
A0 – A9 = Don’t Care)
No–Operation
(RAS = H, CAS = H, WE = H)
The Precharge All command precharges both banks
simultaneously. Both banks are then switched to the idle
state.
The No–Operation command simply performs no opera-
tion (same command as Device Deselect).
Burst Stop
(RAS = H, CAS = H, WE = L)
Write
(RAS = H, CAS = L, WE = L, BA = Bank, A10 = L,
A0 – A9 = Column Address)
The Burst Stop command is used to stop the burst opera-
tion. This command is effective in full page burst operation.
This command assertion in any other burst length operation
is illegal.
The Write command performs the write operation to the
bank designated by BA. The write data is latched to be syn-
chronized to the positive edges of CLK. The length of the
write data (burst length) and column access sequence
(addressing mode) must be programmed in the Mode regis-
ter at power–up prior to the write operation.
Device Deselect
(CS = H)
The Device Deselect command disables the command de-
coder so that the RAS, CAS, WE, and Address inputs are
ignored. This command is similar to the No–Operation com-
mand.
The A9 input is a don’t care for the MC16S084T3B and the
A8, A9 inputs are don’t care for the M116S163AST.
Write with Auto Precharge
(RAS = H, CAS = L, WE = L, BA = Bank, A10 = H,
A0 – A9 = Column Address)
Auto–Refresh
(RAS = L, CAS = L, WE = H, CKE = H,
BA, A0 – A10 = Don’t Care)
The Write with Auto Precharge command performs the
precharge operation automatically after the write operation.
This command must not be interrupted by any other com-
mand.
The A9 input is a don’t care for the MC16S084T3B and the
A8, A9 inputs are don’t care for the M116S163AST.
The Auto–Refresh command is used to refresh the row ad-
dress provided by the internal refresh counter. Both banks (0
and 1) are refreshed alternately by the Auto–Refresh com-
mand and the refresh counter is automatically incremented.
The refresh operation must be performed 4096 times within
64 ms and the next command can be issued after t

the end of the Auto–Refresh command. To provide the Auto–
Refresh command, both banks have need to be in the idle
state. The Auto–Refresh operation is equivalent to the CAS
before RAS operation of the conventional DRAM.
(RAS = H, CAS = L, WE = H, BA = Bank, A10 = L,
A0 – A9 = Column Address)
The Read command performs the read operation to the
bank designated by BA. The read data is issued sequentially,
synchronized to the positive edges of CLK. The length of
read data (burst length), Addressing mode, and CAS latency
(access time from CAS command in clock cycle) must be
programmed in the Mode register at power–up prior to the
write operation.
Self–Refresh Entry
(RAS = L, CAS = L, WE = H, CKE = L,
BA, A0 – A10 = Don’t Care)
The Self–Refresh Entry command is used to enter the
Self–Refresh mode. While the device is in Self–Refresh
mode, all input and output buffers (except the CKE buffer)
are disabled and the refresh operation is automatically

high (Self–Refresh Exit command).
When the precharge operation is performed in a bank dur-

(Figure 22).
When the burst length is full page, column data is repeat-
edly read out until the Burst Stop command or Precharge
command is issued.

can be issued after one clock cycle from the end of this com-
mand.
When the precharge operation is performed in a bank dur-
ing a burst write operation, the burst operation is terminated
(Figure 22).
When the burst length is full page, the input data is repeat-

When the Burst Read and Single Write mode is selected,
the write burst length is one, regardless of the read burst
length.

During a write cycle, the DQM or LDQM/UDQM signal
functions as Data Mask and can control every word of the in-
put data. During a read cycle, the DQM or LDQM/UDQM
functions as the control of output buffers.
The LDQM signal controls DQ0 – DQ7 and the UDQM sig-
nal controls DQ8 – DQ15.
PRECHARGE
The precharge operation is performed by two commands,
Bank Precharge and Precharge All. When the Bank Pre-

MODE REGISTER OPERATION

The Mode register designates the operation mode at the
read or write cycle. This register is divided into three fields: a
Burst Length field to set the length of burst data, an Addres-
sing Mode Selected Bits field to designate the column
access sequence in a burst cycle, and a CAS Latency field to
set the access time at clock cycle.
The Mode register is programmed by the Mode Register
Set command when both banks are in the idle state. The
data to be set in the Mode register is transferred using A0 –
A10 address inputs. The default value of the Mode register
after power–up is undefined; therefore, the Mode Register
Set command must be issued before proper operation.
CAS Latency Field (A6 – A4)
This field specifies the number of clock cycles from the
assertion of the Read command to first read data. The mini-
mum values of CAS latency depend on the frequency of
CLK. The minimum value satisfying the following formula
must be programmed in this field.

Test Mode Entry Bit (A7)
The Self–Refresh mode is entered by providing the Self–
Refresh command (CKE asserted low) when both banks are
in the idle state. The device is in the Self–Refresh mode
while CKE is held low. By entering the Self–Refresh mode,
all input/output buffers (except CKE buffer) are disabled, re-
sulting in lower power dissipation (Figure 13).
This bit is used to enter the test mode and must be pro-
grammed to 0 in normal operation.
Reserved Bits (A8, A10, BA)
These bits are reserved for future operations. They must
be set to 0 in normal operation.
POWER DOWN MODE
Single Write Mode (A9)
When the device enters the Power Down mode, all input/
output buffers (except CKE buffer) are disabled, resulting in
lower power dissipation in standby. The Power Down mode
is entered by asserting CKE low when the device is not oper-
ating the burst cycle. Exit from this mode is performed by tak-
ing CKE high. When CKE goes high, command input must
be No–Operation at next CLK rising edge (Figure 14).
This bit is used to select the write mode. When the A9 bit is
0, Burst Read and Burst Write mode is selected. When the
A9 bit is 1, Burst Read and Single Write mode is selected.

CLK SUSPENSION AND INPUT/OUTPUT MASK
1
While the device is operating in the burst cycle, the internal
CLK is suspended by asserting CKE low and is frozen from
the next cycle. A Read/Write operation is held intact until the
CKE signal is taken high.
The output disable/write mask signal (DQM) has two func-
tions: controlling the output data in a read cycle and perform-
ing word mask in a write cycle. When the DQM is asserted
high at the positive edge of CLK, the output data is disabled
after two clock cycles for a read and the output data is
masked at the same clock cycle for a write. The timing rela-
tion of CKE to DQM is described in Figures 16a and 16b.
REFRESH OPERATION
Two types of refresh can be performed on the device:
Auto–Refresh and Self–Refresh. Auto–Refresh is similar to
the CAS before RAS Refresh of conventional DRAMs and is
performed by issuing the Auto–Refresh command when both
banks are in the idle state. By repeating the Auto–Refresh
cycle, each bank is in turn, refreshed automatically. The re-
fresh operation must be performed 4096 times (rows) within
64 ms (Figure 12). The period between the Auto–Refresh
command and the next command is specified by t
